ScienceDaily (Sep. 9, 2011) — Years of drought had dried up the ancient water supply networks existing around the Mediterranean Rim. However, with rainfall returning over the past 5 years, the hydraulic heritage has come to life again. The names of the tunnels that carry the revived streams -khettaras in Morocco, foggaras in Algeria or qanâts in Iran- evoke the trickling sounds of water. These underground infiltration galleries are the most characteristic and original illustration of local communities’ recovery of ancestral schemes. As IRD researchers and their partners1 show, these water mines in the middle of the desert, most of which had been abandoned, have now been restored by oasis inhabitants.
